SOURCES: U.S. and allies: Defense Department's www.defenselink.mil/news; www.icasualties.org. Iraq civilians: number of deaths due to war-related events since March 2003 as compiled by the private British Web site www.iraqbodycount.net, which bases its count on about 40 media sources and names many of the victims. The toll may be higher since many deaths are never reported.

The Pentagon does not tally civilian casualties. A 2006 survey by Iraqi physicians and overseen by the Johns Hopkins Bloomberg School of Public Health in Baltimore estimated that 655,000 more Iraqi civilians had died since the start of the war than would have died without the invasion.

Between 4,350 and 6,050 Iraqi military personnel died during the U.S.-led invasion in the spring of 2003. Since then, more than 6,300 members of the new Iraqi military and police forces have been killed.
